The Lowdown

Alright, this is Rusty checkin' in from Jaconé. Let's get into it.

Alright, so we've got a bit of a slow start, but the long-range forecast is showing some serious potential. The first few days are pretty ordinary, but hang tight, because the real action kicks off later.

Thursday the 20th is a write-off. The morning is glassy but the swell is a weak 3ft from the east with a short period of 7 seconds, and the combined energy is a measly 141. It's surfable, but nothing to write home about. The afternoon gets worse with a 12 mph easterly wind. Just leave the board in the car.

Friday the 21st is where we start to see a pulse. The morning has a clean 6ft swell from the ENE with a 6 mph offshore wind. The energy is moderate at 466. It's not the best of the week, but it's a solid start to the weekend. The afternoon is a total loss with strong onshore wind.

Saturday the 22nd is a day to sleep in. The morning has onshore wind and the afternoon is a mess of 7ft cross-onshore slop. The wind is just no good.

Sunday the 23rd is better. The morning has a 6ft swell from the SSW with a 9 mph cross-offshore wind. The energy is moderate at 580, and it's clean. The afternoon is pretty similar, but a bit smaller. It's a good day for a session.

Now, Monday the 24th is where things get interesting, but with a caveat. The morning brings a building 8ft S swell with a long period of 13 seconds. The energy is strong at 2000. The wind is cross-shore, so it's a bit choppy. The afternoon, though, is a beast. The swell hits 10ft with a 14-second period and a clean cross-offshore wind. The wave energy is pumping at 3388. This is expert territory only. If you're not a seasoned surfer, stay on the beach.

Tuesday the 25th and Wednesday the 26th are the standouts. The swell drops slightly to 8ft and 7ft, but the period stays long at 13-14 seconds. The wind is offshore or cross-offshore, and the energy is between 1654 and 3001. These are excellent, clean conditions for experienced surfers. The water temp is around 73°F, which is about average for this time of year.

Thursday the 27th drops off a bit, with the swell backing down to 6ft and the wind freshening to 16-19 mph. It's still rideable, but the quality is dropping.

Friday the 28th is a cool little morning session. The swell is a clean 4ft from the south with a 12 mph offshore wind. The energy is moderate at 612. It's a good, clean wave for a longboard or a funboard.

The weekend of the 29th and 30th is small again. The 29th has a 6ft ENE swell but with a short period of 8 seconds. The morning is clean with light offshore wind, and the energy is moderate at 655. It's a fun wave. The 30th is tiny, with 3ft waves and glassy conditions. It's a paddle-around day.

Then, we get a pulse on the 31st. The morning brings a 7ft ENE swell with a light cross-offshore wind. The energy is moderate at 684. It's a good session. The afternoon is a total loss with strong onshore wind, so get your waves in the morning.

The first few days of September are a mix of small, weak, and poorly directed swells. The 2nd and 3rd have some fun-sized waves, but watch out for the 3rd afternoon, which is another 10ft expert-only swell. The 4th has some good 8-8ft SSW swell with clean cross-offshore wind, but it's a long way out, so don't book your flights yet.

To sum it up, the best waves are for the experienced crew on the 24th afternoon through the 26th, with a solid groundswell and clean conditions. The 28th morning and the 29th morning are great for the average surfer. The long-range stuff on the 4th of September is promising, but it's a long way out, so keep an eye on it.

This is Rusty, signing off.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
